A box of mass m1 = 10.0 kg rests on a smooth, horizontal floor next to a box of mass m2 = 5.0kg. You push on the box 1 with a horizontal force of F = 31.8 N:
a.)What net force on box 2 will cause it to have this acceleration?
b.)What the force on box 1 on box 2? (In other words, what is the contact force between the boxes?)
